C12HPASTEURISATION, STERILISATION, PRESERVATION, PURIFICATION, CLARIFICATION OR AGEING OF ALCOHOLIC BEVERAGESMETHODS FOR ALTERING THE ALCOHOL CONTENT OF FERMENTED SOLUTIONS OR ALCOHOLIC BEVERAGES simulation ageing by flavouring C12G3/06 When classifying in this subclass, classification is also made in group B01D15/08 insofar as subject matter of general interest relating to chromatography is concerned. The following IPC groups are not in the CPC scheme. The subject matter for these IPC groups is classified in the following CPC groups: C12H1/044 - C12H1/048 covered by C12H1/0408 C12H1/052 covered by C12H1/0416 C12H1/056 covered by C12H1/0424 C12H1/065 covered by C12H1/061 C12H1/07 – C12H1/075 covered by C12H1/063 C12H1/15 covered by C12H1/003 C12H1/00 C12H1/00Pasteurisation, sterilisation, preservation, purification, clarification, or ageing of alcoholic beverages simulating ageing by flavouring C12G3/06 C12H1/003by a biochemical process C12H1/006using bacterial cultures C12H1/02combined with removal of precipitate or added materials, e.g. adsorption material C12H1/04with the aid of ion-exchange material or inert clarification material, e.g. adsorption material C12H1/0408with the aid of inorganic added material C12H1/0416with the aid of organic added material C12H1/0424with the aid of a polymer C12H1/0432with the aid of ion-exchange material C12H1/06Precipitation by physical means, e.g. by irradiation, vibrations C12H1/061Separation by centrifugation C12H1/063Separation by filtration C12H1/08by heating C12H1/10Precipitation by chemical means C12H1/12without precipitation C12H1/14with non-precipitating compounds, e.g. sulfitingSequestration, e.g. with chelate-producing compounds C12H1/16by physical means, e.g. irradiation C12H1/165by irradiation C12H1/18by heating C12H1/20in containers allowing for expansion of the contents C12H1/22Ageing or ripening by storing, e.g. lagering of beer C12H3/00Methods for reducing the alcohol content of fermented solutions or alcoholic beverage to obtain low alcohol or non-alcoholic beverages C12H3/02by evaporating C12H3/04using semi-permeable membranes C12H6/00Methods for increasing the alcohol content of fermented solutions or alcoholic beverages C12H6/02by distillation C12H6/04by freezing
